According to the Biot-Savart law,we derive the magnetic field of the current-carrying tightly wound
bent solenoid with the rectangular cross section,and obtain the analytic solution. Then,by using the Matlab software,the magnetic fields of three typical ring-shaped structures are shown,and the characters of the magnetic field in the semi ring-shaped structure are discussed in more details.
Key words: solenoid; magnetic field; rectangular cross section; ring-shaped; bent
